Description

Technical Field

[0001] This invention relates to the field of IoT lock technology, and in particular to an IoT lock with remote control function and its usage method. Background Technology

[0002] With societal development, electricity consumption is increasing, leading to a rise in the number of power distribution rooms. Due to the significant safety risks posed by the 10kV high-voltage equipment within these rooms, access must be strictly managed according to regulations. Existing mechanical padlocks are no longer sufficient for modern, information-based management. IoT-enabled electronic locks, with features such as switch operation recording and multiple independent authorization methods, can meet the management requirements for power distribution room access.

[0003] However, most existing locks use mechanical or electronic unlocking. Mechanical unlocking requires a key, which can lead to situations where the key is lost and the lock cannot be opened. Electronic unlocking is simple and convenient to operate, but it has a fixed unlocking password. If the password is leaked, the security of the lock will be greatly reduced. It also lacks the function of dynamically resetting and modifying the password, cannot grant unlocking authority to operators within a specific time limit, and cannot remotely change the password or unlock the lock. This makes it impossible for operators to unlock the lock in time to enter the power distribution room for routine inspections. Summary of the Invention

Based on the determination result, the unlocking command is transmitted to the motor drive module for remote unlocking.

[0015] Optionally, the lock housing includes a first housing, a second housing, and a lock block groove;

[0028] The first cylindrical part and the second cylindrical part are respectively installed at both ends of the round rod;

[0029] An installation groove is formed between the first cylindrical portion and the second cylindrical portion.

[0030] Optionally, the latch assembly includes a handle and a latch rod connected to the handle;

[0048] Based on the judgment result, the drive motor transmission module or the core body rotates so that the balls fall into the groove and generate a gap space.

[0049] Based on the gap space, the engagement between the ball and the pin assembly is released, so that the pin assembly moves upward and generates IoT lock unlocking information.

[0051] 1) This invention sets up a lock housing and a lock block, lock core, motor drive module and circuit control module set inside the lock housing, and sets up two unlocking methods. The first unlocking method is electronic key unlocking. The operator uses an electronic key terminal to insert into the keyhole of this IoT lock.

When the read electronic key is correct, it controls the core body to rotate so that the second ball falls into the arc-shaped groove, and the pin assembly moves up to realize the IoT lock unlocking.

[0052] 2) The second unlocking method is remote unlocking. When the circuit control module receives the unlocking command and electronic key sent by the remote terminal, it reads the electronic key from the remote terminal. If the read electronic key is correct, the connecting seat of the motor drive module rotates, causing the first ball to fall into the positioning groove. The second ball moves towards the first ball. At this time, there is a certain gap between the bolt assembly and the other second ball. The bolt assembly moves upward to unlock the IoT lock. This IoT lock has multiple unlocking methods and can remotely control the opening and closing of the lock body, making it more convenient to use. Attached Figure Description

[0064] This invention provides an IoT lock with remote control functionality and a method for using it, which solves the technical problem that existing IoT locks cannot remotely change passwords or unlock, thus preventing operators from timely unlocking and entering the power distribution room for routine inspections.

[0065] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0066] Example 1

[0067] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of an IoT lock with remote control function provided in Embodiment 1 of the present invention.

[0068] This invention provides an IoT lock with remote control functionality. The IoT lock includes a lock housing 1 and a lock block 8, a lock core 2, a motor drive module 4, and a circuit control module 6 disposed inside the lock housing 1. The lock core 2 includes a core body 210, a ball bearing assembly 220, and an electromagnetic lock core 230. The motor drive module 4 and the electromagnetic lock core 230 are respectively connected to the circuit control module 6. The electromagnetic lock core 230 is disposed inside the core body 210 and located on one side of the keyhole 111 inside the lock housing 1. The ball bearing assembly 220 includes multiple first balls 221 and multiple second balls 222. The core body 210 has a ball bearing through hole inside. 211; The inner wall of the lock housing 1 is provided with a mounting groove 113, and the ball bearing through hole 211 and the mounting groove 113 are connected to form a hollow groove 3 for accommodating the first ball bearing 221 and the second ball bearing 222; a motor drive module 4 is provided at one end of the hollow groove 3, and a pin assembly 5 is provided at the other end; the pin assembly 5 extends into or disengages from the lock hole on the lock block 8; the circuit control module 6 is electrically connected to the motor drive module 4 and the electromagnetic lock core 230 respectively; the circuit control module 6 is used to receive the unlocking command and the electronic key, and to determine whether the electronic key is consistent with the preset electronic key, and to transmit the unlocking command to the motor drive module 4 for remote unlocking according to the judgment result.

[0069] It should be noted that the circuit control module 6 of this IoT interlock stores key data related to the unlocking action.

[0070] like Figure 2As shown, the ball bearing through hole 211 and the mounting through groove 113 coaxially arranged therein are connected to form a hollow through groove 3, which can accommodate multiple first balls 221 and second balls 222. When the first ball bearing 221 falls, the second ball bearing 222 can move towards the first ball bearing 221, and when the second ball bearing 222 falls, the first ball bearing 221 can move towards the second ball bearing 222. Regardless of whether the first ball bearing 221 or the second ball bearing 222 falls, the second ball bearing 222, which was originally in a snap-fit ​​relationship with the pin assembly 5, now has a gap space between it and the pin assembly 5. The pin assembly 5, which is detached from the second ball bearing 222, moves upward and disengages from the lock hole on the lock block 8, thus unlocking the IoT lock.

[0071] In practical implementation, the IoT lock has two unlocking methods. The first unlocking method is electronic key unlocking. The operator uses an electronic key terminal 7 to insert into the keyhole 111 of the IoT lock and contact the electromagnetic lock core 230 on one side of the keyhole 111. The electromagnetic lock core 230 reads the electronic key from the electronic key terminal 7 and compares the read electronic key with the pre-stored key data. When the read electronic key is correct, the core body 210 is controlled to rotate. When the arc-shaped groove 212 on the outer wall of the core body 210 rotates to the position of the second ball 222, the second ball 222 falls from the mounting slot 113 into the arc-shaped groove 212. At this time, there is a certain gap space between the pin assembly 5 and the other second ball 222. The pin assembly 5 can move upward to unlock the IoT lock.

[0072] The second unlocking method is remote unlocking. When the circuit control module 6 receives the unlocking command and electronic key sent by the remote terminal, it reads the electronic key from the remote terminal and compares it with the pre-stored key data (i.e., the preset electronic key). If the read electronic key is correct, it sends an unlocking command to the servo motor 410 of the motor drive module 4 to drive its connecting seat 430 to rotate. When the positioning groove 431 of the connecting seat 430 rotates to the position of the first ball 221, the first ball 221 falls from the ball through hole 211 into the positioning groove 431. There is a gap between the second ball 222 and the first ball 221, so that the second ball 222 moves towards the first ball 221. At this time, there is a certain gap space between the latch assembly 5 and the other second ball 222, and the latch assembly 5 can move upward, so that the IoT lock can be remotely unlocked. This IoT lock has multiple unlocking methods and can realize remote control of the lock body opening and closing, making it more convenient to use.

[0073] In this embodiment of the invention, the implementation also includes a ticket-based work monitoring function, specifically monitoring whether the basis for unlocking is "correct". The ticket-based work monitoring function can have two forms: the circuit module (circuit control module 6) of this IoT lock stores key data related to this unlocking action, such as... Figure 3As shown, when the worker's electronic key terminal 7 is inserted into the keyhole 111 of this IoT lock, the electromagnetic lock cylinder 230 contacts the electronic key terminal 7. The electromagnetic lock cylinder 230 is electrically connected to the circuit module (circuit control module 6) via a wire, reads the electronic key from the electronic key terminal 7, and compares it with the pre-stored key data. If they match, the lock is unlocked. In this embodiment, the "work ticket" is similar to electronic work order data. This IoT lock can communicate with the backend system wirelessly or via wired means. The communication method is existing technology and will not be described in detail here. In another preferred embodiment, when a worker unlocks the door, the electronic key terminal 7 is inserted into the keyhole 111 of the IoT lock, triggering the IoT lock to send information to the backend system to obtain the latest "work ticket" data. The "work ticket" data includes information such as the operator, operation details, and electronic key within a preset time period. After receiving the "work ticket" data, the IoT lock compares it with the information stored in the external electronic key terminal 7 for this operation. If the comparison matches, the door unlocks, and the worker's actions are monitored. If the comparison does not match, feedback is sent to the backend system for display. This ticket-based work method improves the security level of workplace access management.

[0074] This IoT lock is connected to the network, and the IoT lock backend management system connected to this IoT lock can send the "work ticket" content to this IoT lock. The lock opening and closing of this IoT lock is matched with the work ticket content, which can realize the "work with ticket" monitoring function. This function greatly improves the security level of access management at the workplace.

[0075] Example 2

[0076] Please refer to the figure. Figure 1 , Figure 2 , Figures 4 to 6 , Figure 1 This is a three-dimensional structural diagram of an IoT lock with remote control function provided in Embodiment 2 of the present invention.

[0077] This invention provides an IoT lock with remote control functionality. The lock housing 1 includes a first housing 110, a second housing 120, and a lock block groove 112. The first housing 110 and the second housing 120 cooperate to form a cavity for accommodating the lock block 8, the lock core 2, the motor drive module 4, the circuit control module 6, and the bolt assembly 5. The first housing 110 is provided with an installation through groove 113 and a keyhole 111. The lock block 8 is disposed inside the lock block groove 112. An arc-shaped groove 212 is provided on the outer wall of the core body 210. The arc-shaped groove 212 is used to accommodate a second ball bearing 222 that falls out when an external electronic key terminal 7 extends into the keyhole 111, contacts the electromagnetic lock core 230, and rotates the core body 210.

[0078] It should be noted that, for reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first housing 110 and the second housing 120 cooperate to form a receiving cavity for accommodating the lock block 8, the lock core 2, the motor drive module 4, the circuit control module 6, and the bolt assembly 5. The first housing 110 is provided with a mounting through groove 113 and a keyhole 111.

[0079] The lock housing 1 also includes a lock block groove 112, in which a lock block 8 is disposed. When the operator inserts the external electronic key terminal 7 into the keyhole 111 to contact the electromagnetic lock cylinder 230 and rotates the cylinder body 210, the arc-shaped groove 212 on the outer wall of the cylinder body 210 faces the second ball 222. Due to the mutual compression between the multiple second balls 222, the second balls 222 move towards the arc-shaped groove 212 and fall into the arc-shaped groove 212, thereby causing the bolt assembly 5 to move upward to unlock.

[0080] Example 3

[0081] Please see Figure 2 , Figure 4 and Figure 7 , Figure 2 This is a cross-sectional structural diagram of an IoT lock with remote control function provided in Embodiment 3 of the present invention.

[0082] This invention provides an IoT lock with remote control functionality. The motor drive module 4 includes a servo motor 410 and a connecting seat 430. A positioning groove 431 is provided on the outer wall of the connecting seat 430. The servo motor 410 drives the connecting seat 430 to rotate, pushing a first ball bearing 221 into the positioning groove 431. A limiting groove 432 is provided on the connecting seat 430. A positioning pin 121 is fixed on the second housing 120, and the positioning pin 121 is located inside the limiting groove 432. The positioning groove 431 and the limiting groove 432 are connected. A round rod 434 is provided on the connecting seat 430. A first cylindrical portion 433 and a second cylindrical portion 435 are respectively installed at both ends of the round rod 434. An installation groove is formed between the first cylindrical portion 433 and the second cylindrical portion 435.

[0083] It should be noted that, for reference Figure 2As shown, a positioning groove 431 is provided on the outer wall of the connector 430. When the servo motor 410 drives the connector 430 to rotate, the positioning groove 431 on the outer wall of the connector 430 is turned towards the first ball 221. Due to the mutual compression between the multiple first balls 221, the first balls 221 move towards the positioning groove 431 and fall into the positioning groove 431. At the same time, the second ball 222 moves towards the first ball 221. At this time, the second ball 222, which was originally in a snap-fit ​​relationship with the pin assembly 5, has a gap space between it and the pin assembly 5. The pin assembly 5, which is detached from the second ball 222, moves upward and disengages from the lock hole on the lock block 8, thus unlocking the IoT lock.

[0084] See Figure 4 As shown, the connecting seat 430 is provided with a limiting groove 432, and the second housing 120 is fixed with a positioning pin 121, which is located in the limiting groove 432. The setting of the limiting groove 432 can limit the rotation angle of the connecting seat 430, and prevent the first ball 221 from being difficult to reset due to over-rotation of the connecting seat 430. The design is more ingenious and easier to use. Furthermore, the limiting groove 432 is connected to the positioning groove 431, making the design space more compact.

[0085] See Figure 7 As shown, the connecting seat 430 is provided with a first cylindrical part 433, a round rod 434 and a second cylindrical part 435. The first cylindrical part 433 and the second cylindrical part 435 are respectively installed at both ends of the round rod 434. An installation groove is formed between the first cylindrical part 433 and the second cylindrical part 435. The first housing 110 is provided with a position for installing the connecting seat 430, so that the connecting seat 430 can be quickly installed and fixed in the first housing 110, which is convenient to use.

[0086] Furthermore, the servo motor 410 is also provided with a connecting shaft 420, which is fixedly connected to the connecting seat 430 and drives the connecting seat 430 to rotate.

[0087] Example 4

[0088] Please see Figure 2 , Figure 2 This is a cross-sectional structural diagram of an IoT lock with remote control function provided in Embodiment 4 of the present invention.

[0089] This invention provides an IoT lock with remote control functionality. The latch assembly 5 includes a handle 510 and a latch rod 520 connected to the handle 510. An annular groove 521, adapted to a second ball bearing 222, is axially provided around the middle of the latch rod 520. The second ball bearing 222 abuts against the annular groove 521. A positioning protrusion 522 is axially provided around the lower part of the latch rod 520. A return spring 530 is sleeved at the bottom of the latch rod 520, with one end abutting against the positioning protrusion 522 and the other end abutting against the first housing 110. The diameter of the first ball bearing 221 is smaller than the diameter of the second ball bearing 222. The diameter of the ball bearing through hole 211 is smaller than the diameter of the mounting through groove 113. The diameter of the second ball bearing 222 is larger than the diameter of the ball bearing through hole 211. The first ball bearing 221 is located inside the ball bearing through hole 211, and the second ball bearing 222 is located inside the mounting through groove 113.

[0090] It should be noted that, for reference Figure 2 As shown, the bolt assembly 5 includes a bolt rod 520, with an annular groove 521 and a positioning protrusion 522 respectively arranged around its axial direction. The annular groove 521 and the positioning protrusion 522 are respectively located in the middle and bottom of the bolt rod 520. The second ball 222 abuts against the annular groove 521 to restrict the bolt assembly 5 from moving upward. In the unlocked state, the second ball 222, which was originally abutting against the annular groove 521, can move towards the first ball 221, that is, away from the bolt assembly 5. At this time, the bolt assembly 5 can move upward to unlock. In the locked state, the second ball 222 is restricted to the mounting groove 113 and cannot move left or right. At this time, the second ball 222 abuts against the annular groove 521, restricting the bolt assembly 5 from moving upward, thereby unlocking the lock.

[0091] The latch assembly 5 also includes a return spring 530, a positioning protrusion 522, and an annular locking position for placing the return spring 530 in the first housing 110. The return spring 530 is sleeved on the latch rod 520, with one end of the return spring 530 abutting against the first housing 110 and the other end abutting against the positioning protrusion 522. When unlocking, the operator grips the handle 510 to move the latch rod 520 upward, and the latch rod 520 extends out of the locking block 8 without restricting the movement of the locking block 8, allowing the cabinet door to be opened. When the operator releases the handle 510, the latch rod 520 returns to its initial state under the action of the return spring 530. By setting the return spring 530, the latch rod 520 is normally closed when not subjected to external force, which can effectively prevent the cabinet door from being left unlocked.

[0092] See Figure 2As shown, the diameter of the first ball bearing 221 is smaller than the diameter of the second ball bearing 222, the diameter of the ball bearing through hole 211 is smaller than the diameter of the mounting groove 113, and the diameter of the second ball bearing 222 is larger than the diameter of the ball bearing through hole 211. The first ball bearing 221 is located inside the ball bearing through hole 211, and the second ball bearing 222 is located inside the mounting groove 113. Therefore, using balls of different sizes makes the locking and unlocking process of the lock more stable. Because the diameter of the larger second ball bearing 222 is slightly larger than that of the ball bearing through hole 211, the range of motion of the first ball bearing 221 and the second ball bearing 222 can be controlled, facilitating stable transmission.

[0093] Example 5

[0094] Please see Figure 2 , Figure 4 and Figure 5 , Figure 2 This is a cross-sectional structural diagram of an IoT lock with remote control function provided in Embodiment 5 of the present invention.

[0095] This invention provides an IoT lock with remote control functionality. The first housing 110 has a circular mounting slot 114; the core body 210 is installed inside the circular mounting slot 114. The circuit control module 6 includes a first magnetic sensor 61 and a second magnetic sensor 62. The first magnetic sensor 61 is used to sense the lock block 8; the second magnetic sensor 62 is disposed inside the core body 210 and is used to convert the rotational motion information of the core body 210 into an electrical signal and output the electrical signal.

[0096] It should be noted that, for reference Figure 5 As shown, the core body 210 is installed in the circular mounting slot 114. The first shell 110 can be integrally formed, making the structure more compact and convenient to use.

[0097] See Figure 2 and Figure 4 As shown, the circuit control module 6 includes a first magnetic sensor 61 for detecting the lock block 8; the first magnetic sensor 61 cooperates with the lock block 8 to convert the unlocking or unlocking action of the lock block 8 and the bolt rod 520 into an electrical signal, which helps to confirm whether the current state is actually open and closed, and facilitates subsequent alarms for abnormal states.

[0098] Furthermore, the circuit control module 6 also includes a second magnetic sensor 62, which is located inside the core body 210. The second magnetic sensor 62 is used to convert the rotation of the core body 210 into an electrical signal and output an electrical signal, which helps to confirm whether the core body 210 is rotating in the current state, and facilitates subsequent alarms for abnormal states.

[0099] In practical implementation, the electrical signals of the first magnetic sensor 61 and the second magnetic sensor 62 are uploaded to the background system via this IoT interlock. If the analysis determines that the electrical signal of the first magnetic sensor 61 indicates that the door is open, which is inconsistent with the preset current state, an alarm can be displayed; or if the analysis determines that the electrical signal of the second magnetic sensor 62 indicates that there is no rotation, which is inconsistent with the preset current state, an alarm can be displayed.

[0103] Step 601: Obtain the electronic key;

[0104] Step 602: Determine whether the electronic key matches the preset electronic key;

[0105] Step 603: Drive the motor transmission module 4 or the core body 210 to rotate according to the judgment result so that the ball falls into the groove and generates a gap space.

[0106] Step 604: Based on the gap space, release the locking relationship between the ball and the pin assembly 5 so that the pin assembly 5 moves upward and generates IoT lock unlocking information.

[0107] It should be noted that the IoT lock has two unlocking methods. The first unlocking method is electronic key unlocking. The operator uses the electronic key terminal 7 to insert into the keyhole 111 of the IoT lock and contact the electromagnetic lock cylinder 230 on one side of the keyhole 111. The electromagnetic lock cylinder 230 reads the electronic key from the electronic key terminal 7 and compares the read electronic key with the pre-stored key data. If the read electronic key matches the pre-stored key data, the cylinder body 210 is controlled to rotate. When the arc-shaped groove 212 on the outer wall of the cylinder body 210 rotates to the position of the second ball 222, the second ball 222 falls from the mounting slot 113 into the arc-shaped groove 212. At this time, there is a certain gap space between the bolt assembly 5 and the other second ball 222. The bolt assembly 5 can move upward to unlock the IoT lock.

[0108] The second unlocking method is remote unlocking. When the circuit control module 6 receives the unlocking command and electronic key sent by the remote terminal, it reads the electronic key from the remote terminal and compares it with the pre-stored key data. If the read electronic key is correct, the servo motor 410 of the motor drive module 4 drives its connecting seat 430 to rotate. When the positioning groove 431 of the connecting seat 430 rotates to the position of the first ball 221, the first ball 221 falls from the ball through hole 211 into the positioning groove 431. There is a gap between the second ball 222 and the first ball 221, so that the second ball 222 moves towards the first ball 221. At this time, there is a certain gap space between the latch assembly 5 and the other second ball 222, and the latch assembly 5 can move upward to enable the IoT lock to unlock. This IoT lock has multiple unlocking methods and can realize remote control of the lock body opening and closing, making it more convenient to use.

[0109] In this embodiment of the invention, the implementation also includes a ticket-based work monitoring function, specifically monitoring whether the basis for unlocking is "correct". The ticket-based work monitoring function can have two forms: the circuit module (circuit control module 6) of this IoT lock stores key data related to this unlocking action, such as... Figure 3 As shown, when the worker's electronic key terminal 7 is inserted into the keyhole 111 of this IoT lock, the electromagnetic lock cylinder 230 contacts the electronic key terminal 7. The electromagnetic lock cylinder 230 is electrically connected to the circuit module (circuit control module 6) via a wire, reads the electronic key from the electronic key terminal 7, and compares it with the pre-stored key data. If they match, the lock is unlocked. In this embodiment, the "work ticket" is similar to electronic work order data. This IoT lock can communicate with the backend system wirelessly or via wired means. The communication method is existing technology and will not be described in detail here. In another preferred embodiment, when a worker unlocks the door, the electronic key terminal 7 is inserted into the keyhole 111 of the IoT lock, triggering the IoT lock to send information to the backend system to obtain the latest "work ticket" data. The "work ticket" data includes information such as the operator, operation details, and electronic key within a preset time period. After receiving the "work ticket" data, the IoT lock compares it with the information stored in the external electronic key terminal 7 for this operation. If the comparison matches, the door unlocks, and the worker's actions are monitored. If the comparison does not match, feedback is sent to the backend system for display. This ticket-based work method improves the security level of workplace access management.
